CALEN DAR-CLOCK.

SSPEGIFICATION forming part of Letters Patent No. 543,237, dated July23, 1895.

Application filed April 18, 1895- Serial No. 546,228! (No model.)

To (LZZ whom it may concern:

Be it known that 1, CHARLES I. FOWLER, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Calendar-Clocks, of which the followingis a specification.

The object of this invention is to providea calendar-clock of simpleconstruction, and which is easily set and manipulated; and the inventionresides in the novel features of construction set forth in the followingspecification and claims, and illustrated in the annexed drawings, inwhich- Figure 1 is a side elevation of a calendarclock, the case beingsectioned open for exposure. Fig. 2 is a front elevation of awinding-lever with a clock-movement. Fig. 3 is asection along 3 3, Fig.4, showing a calendarmovement. Fig. at is a plan view of thecalendar-movement.

The casing 1 has three windows or sightopenings 2 3 4. Through window2the clock dial and hands are exposed to View. Through window 3 the dayof the week is exposed, the week-days being noted on the faces of theheptagonal roller 6; Through window 4: the date or day of the month isexposed, these dates being noted on date-strip 7, which is drawn orrolled oif from delivery-roller 8 by the friction or propelling roller 9onto takeup roller 10. The pulleys 11 and 12 with belt 13 cause thetake-up roller 10 to rotate with delivery-roller 8.

The pulley and belt connection 11, 12, and 13 is such that the take-uproller 10 has always a tendency to rotate faster than the deliveryroller8, so as to take up any slack in strip 7, but said roller 10 is neverallowed to draw any portion of the strip from the deliveryroller, asirregularities might thus occur in consequence of the constantly-varying diameters of the rolls on rollers 8 and 10. The belt 13 is thereforemade so slack or of such springy or elastic material, and the pulleys 11and 12 are so smooth that any motion in excess of that required to makeroller 10 take up the slack of the date-strip is lost as regards saidroller 10 by the pulley 11 slipping with relation to belt 13 or by saidbelt slipping with relation to pulley 12.

Pressure of a spring 52, Fig. 1, on delivery roller 8 will aid inpreventing the improper rotation of rollers 8 and 10. The stripis thustaken from roller 8 in a uniform and proper successive step-by-stepmotion by the propelling-roller 9, and weighted arms may be applied, asknown, to cause the strip 7 to lie firmly against or part way aboutroller 9, to be securely gripped or propelled by the latter. Foradditional gripping the surface of roller 9 may be sanded or roughened.

The day-roller 6 and driving-roller 9, as will presently appear, aredriven by a spring or motor 53, Fig. 1, wound by ratchet and pawl 15 and16, Fig. 3, said pawl 16 being mounted on and actuated by arm 17,oscillated by link 18 and lever 19, Fig. 2, fulcrumed at 21. This lever19 extends transversely across a clock-movement and onto or into thepath of a stud 22 (one or more) carried by wheel or by drum 23 of theclockmovement. As the studded wheel or drum 28 rotates to carry aboutthe stud 22 the consequent rise and fall of lever 19 will oscillate arm17 to wind the spring or motor 53, sothat the winding of this motor 53is accomplished automatically.

The lockpawl 51 preserves the tension or energy of the motor 53 untilneeded. This motor, by means of gear 55, Fig. 3, imparts motion to thedriving-gear 56, engaging the gears 57 and 58, secured to the shafts ofrollers 6 and 9. The wheel 56 is held against rotation byhaving an eyeor depression 59, Fig. 3, in its side engaged by a tooth 60 on lever 61,fulcrumed at 63 to a suitably-applied frameplate. The lever 61 isapproximately 1- shaped for bringing the tooth 60 into proper positionto engage into the eyes 59, as required. The spring 6% tends to movelever 61 into position for the tooth 60 to engage into an eye 59. Inaddition to tooth or detent- 60 the lever 61 carries an arm 65, Fig. 3,which is adapted to act as a detentfor the fly 66 of the calendar-movingtrain driven by motor 53.

The lever 61, as will'presently appear, is actuated at the suitableperiod, or midnight, against the force of spring 64 to release thedetents 60 and 65, so that the calendar-moving train, with the rollers 6and 9, will move the next succeeding day and date into exposure, afterwhich the detents 60 and 65 again come into arresting action.

The detent should, of course, be held out of action until the wheel 56has fairly started to carry the eye 59, just released by detent 60, outof reach or past said detent, so that the .wheel 56 will give therollers 6 and 9 the moves with the tooth 60 to releasing position awayfrom wheel 56,said spring 68 will draw or snap the arm 67 in between thelever 61 and the wheel 56, so as to hold the tooth 60 away I fromengagement until, by the rotation of wheel 56, the eye 59 just releasedby tooth 60 has traveled out of reach of said tooth and one of the studs69, projecting from a side of said wheel, has been carried against arm67 to move the latter out of the way of lever or arm 61, so that thisarm is free to be moved by spring 64: back to engaging position forlocking tooth 60 into the next succeeding eye 59. The eyes 59 areproperly spaced with relation to the calendar-moving train, so thatbetween a successive release and arrest by tooth 60 this train will movesufficiently to cause the rollers 6 and 9 to make an advance for a dayand a date.

In the drawings the wheel 56 is shown with four eyes 59 and four studs69; but this number of eyes and studs can manifestly be varied asrequired by varied gearing or speeding of the calendar-moving train.

The arm 61 when moved to release or engage detent 60 will, of course, atthe same time release or engage the fly detent 65.

The cylinders 6 and 9 being secured to their gears 57 and 58 by screws84, the loosening of said screws will enable the cylinders to be set asrequired without affecting the gears.

In addition to'the fly-detent another flydetent 85 and 86, carried bythe winding'arm 17, will have its free end 86 in the way of said fly toprevent its rotation while the arm 17 is in elevated position, orrising, or while said arm 17 makes a winding stroke, but when said armoscillates down or drops on its return from a winding stroke, the detent85 86 will be out of the way of the fly. A suitably slotted orperforated post 87 will guide the detent 85 86 in its oscillations witharm 17.

The lever 61 is shown with a projecting incline or nose 89, Fig. 4, andthe ratchet 15 is shown provided with a stud 70, said ratchet beingrotated so as at the proper time, say midnight or thereabouts, to moveor sweep the stud past the suitably-projecting nose or part 89 of lever61 to press the latter to releasing position against the action ofspring 64. The driving gear 56 will be released as thereleasing-movement of lever 61 withdraws tooth 60 from the driving-gear.to allow the latter to properly advance cylinders 6 and 9.

The ratchet 15 should be so set that the stud 70 while sweeping pastnose 89 will never come to rest while in contact with said nose, so thatthe lever 61, after a releasing movement will not fail to properlyre-engage its tooth 60 with driving-gear 56.

The lever 19, actuated by studs 22 on wheel I or drum 28, has a shoulder88 for the engagement or impact of studs 22, said shoulder beingrecessed or re-entering to allow a stud 22 to enter said recess forpermitting the setting back of the clock-movement for a certaindistance.

The clock-movement can be driven by any suitable power, as an electricmotor, or a spring or weight, as known.

What I claim as new, and desire to secure by Letters Patent, is-

1. A calendar movement and a motor train therefor, provided with a fly,combined with a winding arm for winding the motor, and fly detents andreleasing mechanism substantially as described, one of said fly detentsbeing carried by said arm substantially as described.

2. A calendar movement and a motor therefor, combined with a windingratchet and pawl for said motor, a driving gear actuated by said motor,and a detent lever made to extend past the ratchet and into engagementwith the driving gear, said ratchet having a releasing-stud for thedetent lever substantially as described.

3. A calendar movement and a motor therefor, combined with a windingratchet and pawl for said motor, a driving gear actuated by said motor,and a detent for said driving gear, said ratchet having a releasing studfor the detent, and said detent having an incline or nose placed in thepath of the releasing stud substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
